May 2019 Wing lift BNAPS News July 2020 BNAPS News Vol 10 Iss 4 – July 2020 BNAPS Restoration Workshop is Re-opened - Plan for the Future of Islander G-AVCN in 2021 BNAPS Trustees have devised a working regime, in consultation with the restoration team, and taking account of the emergency restrictions in place at the time, that allowed restoration work to be resumed from 16 July 2020. BNAPS Restoration Team meeting at the restoration workshop, 9 July 2020 The aim is to complete all essential restoration work items by the end of September 2020 and then to dismantle the aircraft and prepare it for transport to temporary storage. The main work items include completion of fuselage lining and detail decals, fabrication and installation of internal fuselage and door trim panels, installation of the propellers and spinners, installation of an alternator for the starboard engine and painting the engine cowlings. This work will be progressed during the coming months, although installation of the propellers and spinners and the alternator require sourcing of essential missing parts. However, where work is not completed by the end of September it is feasible to delay some of the work and finish it off when the aircraft is in storage or include it as part of the process of preparation for re-assembly of the aircraft when suitable display space is accessible. At this stage BNAPS Trustees are in discussion with an established museum located on the Isle of Wight and full details will be revealed in due course when agreements are in place. During the past few months it has become apparent that a move into storage was best undertaken sooner rather than later, partly because of the financial burden if the occupation of the Brickfields workshop was extended into 2021 and the fact that, if necessary, any remaining work items can be undertaken with the fuselage and wing as separate parts at a later stage and in another location. In this issue of BNAPS News: B-N Gives Go Ahead for Islander MK.III London -Victoria Air Race Plus more news of Islanders and Trislanders around the World 1 BNAPS Chairman’s Update – July 2020 2010 2016 2020 Dear BNAPS Supporter, The “lock down” period has given the opportunity to take stock of what the restoration project has achieved so far and look again at the way ahead that would enable our restored B-N Islander G-AVCN to move to a stage where it can be on public display. As outlined on page 1 of this issue of BNAPS News the immediate plan of campaign is get the restoration work restarted and reach a stage by the end of September when the aircraft can be dismantled and moved into storage. In this respect a pair of adjustable wing stands at present under construction are critical in enabling the wing and fuselage to be separated and for transportation of the wing. At present it seems unlikely that BNAPS will be able to hold a final workshop open day at the end of September, as in previous years, in support of the Isle of Wight High Sheriff’s “Isle of Wight Day” initiative. For 2020 the event would also serve to mark the end of the restoration phase of the project and also commemorate the 50th anniversary of the first flight of the Islander Mk.III, or Trislander, G-ATWU, that took place from Bembridge Airport on 11 September 1970. If the present restrictions on public gatherings are still in place in September then, unfortunately, it will not be possible for the workshop open day to go ahead. The situation regarding restrictions is in a state of continuous change and is being monitored accordingly, both in respect of the possibility of a workshop open day event and the health and safety of the restoration team. BNAPS Trustees continue to seek various ways and sources of funding to ensure the project can continue to a successful conclusion as planned. For more information regarding the above please contact BNAPS by email [email protected] or Telephone 01329 315561. Yours sincerely, Bob Wealthy, Britten-Norman Aircraft Preservation Society Chairman th Trislander 50 Feature Article Planned for Airliner World September 2020 Issue. Airliner World’s Assistant Editor, Martin Needham, has recently been in touch with BNAPS and asked for assistance to the preparation of a five page feature article on the th B-N Trislander and the 50 anniversary of its first flight that is planned for inclusion in the September 2020 issue of the magazine, due out on 13 August. Airliner World now includes a heritage section. In the May 2020 issue the restoration of Islander G-AVCN was the subject of a half page news item. 2 G-AVCN Restoration Progress – July 2020 As of 16 July, 2020, the restoration work was re-started in the workshop. After about 4 months away from the project the restoration team spent some time catching up with the work that had been in progress back in March. The main activities now under way are summarised below: 1 Bob Wilson set about cleaning off a layer of dust that had settled on the aircraft and Bernie Coleman nobly volunteered to pump up the tyres. The tyres had not lost much pressure over the 4 month lay-off. Bernie Coleman is seen here in action using the foot pump to re-inflate the tyres. 2 Bob Wilson and Guy Palmer reviewed the fuselage line painting situation, in consultation with spray painting specialist Bill Mason, regarding application of the black fuselage lining and restoration of an area of the port side nose section, where an earlier application of black lining had not been satisfactory and had to be removed. Also discussed were arrangements for spray painting the engine cowlings off site at Bill Mason’s spray painting facility. 3 Paul Thomasson continued with fabrication of plastic door surround trim mouldings. 4 The new wing-stand frames arrived at the workshop, thanks to the efforts of Paul Thomasson. He and Bob Ward installed the wheels and the wings stands now await the adjustable threaded fittings which are expected in the near future. The adjustable wing-stand frames with wheels installed. 5 Mark Porter continued with final fitting and adjustments of the starboard engine cowlings. 6 Bryan Groves has updated the missing parts list and prepared exhaust system support brackets ready for installation at a later stage. 7 Patrick Gallagher resumed work on the wing/fuselage fairings temporary fit. Paul Brook picked up the work on the electrics in the wing to fuselage area. 8 Bernie Coleman continued with riveting in a roof skin section on the fuselage of Islander VQ-SAC. 9 A start was made on clearing out a quantity of scrap metal and surplus items that had been accumulated during the project. 3 G-AVCN Restoration Project Status – July 2020 The work items that are necessary to complete the restoration project are summarised below: Islander G-AVCN Restoration Work Items 1 Wing and Engines: 1.1 Complete the height adjustable wing support trestles including profile boards. 1.2 Complete engine dressing. 1.3 Fit propellers complete fitting of the engine cowlings and fairings ready for painting. 1.4 Paint engine cowlings and fairings. 1.5 Fabricate fairings that fit between the in board side of the top engine cowlings and wing leading edge droop. 2 Fuselage: 2.1 Ongoing internal trimming work. 2.2 Continue application of the cheat lines. 2.3 Complete the wing to fuselage fairings temporary fit Islander VQ-SAC Fuselage Section Work Items: 1 Prepare exterior surfaces and etch prime 2 Install windows in fuselage and doors 3 Fabricate door hinges and install doors 4 Fabricate and install door trim panels and sidewall trim 5 Fabricate and install instrument panel blank and centre console 6 Install coaming 7 Install desktop flight simulator equipment 8 Install electrical earthing connection for fuselage structure 9 Commission flight simulator 4 B-N Gives Go Ahead for Islander BN-2A Mk.III Introduction Ever since the prototype Islander had flown B-N had looked at several design schemes design for a larger transport aircraft. These schemes ranged for a scaled up Islander, referred to as the Mainlander and seen as a “Dakota replacement” (not to be confused with the Mainlander that emerged in the Fairey Britten-Norman era in 1972). With this in mind the BN-2A Mk.II Islander Super, with up to 14 seats, was built and flown in 1969 and the 21 seat BN-4 design scheme appeared in 1969. The early success of Aurigny Air Services Islander operations inspired a requirement for a larger capacity aircraft having the key attributes of the Islander. From this melting pot of ideas and needs John Britten summarised the thinking at the time in a lecture he gave to the RAeS Reading Branch in March 1971: “Growth is essential to any company's health and in aircraft manufacture cannot be sustained without successful innovation. Once our production headaches were cured we began to spare a little time for planning future growth. The most significant step forward that we have taken from the original Islander concept followed the realisation that the world's transport aircraft safety requirements seemed to be designed to favour three-engined aircraft and the appreciation that a third engine would not only be relatively easy to install on an Islander but would give many practical advantages. The design that Desmond Norman and I sketched in a Chicago motel late in 1969 had obvious potential structural and aerodynamic problems.
